Introduction to Network Fundamentals: Network+ Certification Prep

An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for locating and communicating with devices on a network, rather than indicating a physical location or being used for authentication purposes.

In networking, a backbone refers to the central infrastructure that links different parts of the network together, facilitating communication and data transfer between various segments and devices.

Creating a backup involves making a copy of critical data files to ensure they are safe and can be recovered in case of loss or damage.

A client is a computer or device that uses the services provided by a server, not the one that provides services.

Client/Server architecture/network is characterized by the presence of a central server that stores data and resources which are then shared with clients. This architecture promotes efficient communication and resource utilization.

A connectivity device is specifically designed to facilitate the connection and communication between networks or various parts of a network, enabling the exchange of data and resources.

A data packet is specifically a unit of information sent from one node to another across a network, not a virus, physical device, or software program.

A HOST refers to a computer that acts as a central point for resource sharing in a network, allowing other computers to access its resources. It is not related to bread, television shows, or musical instruments.

LAN stands for Local Area Network, which is a network that covers a small geographic area, such as a single building or office space, allowing devices within that area to communicate with each other.

A Metropolitan Area Network (MAN) refers to a network that covers a larger area than a Local Area Network (LAN) and can connect buildings or areas within a city.

A WAN is a network that covers a broad area, connecting multiple LANs across long distances. It is commonly used to connect geographically dispersed locations such as offices or data centers.

A file server is a dedicated server used for sharing applications and data among clients, it provides file services enabling users to access and store files centrally.

Topology refers to the way in which components of a network are arranged and how they communicate with each other. It defines the structure of a network.

Peer to Peer architecture allows all computers on the network to communicate directly with each other, eliminating the need for a central server to manage connections.

In the context of networking, a NODE refers to a computer or device connected to a network with its own unique address, capable of sending and receiving data.

NOS commonly refers to Network Operating System, which is used to manage network resources and provide services to users. Examples include Server 2003, Slaxware Server, UNIX, and Linux.

A workstation in the context of computing refers to a computer that is used for work-related tasks and is typically connected to a network. It is different from a piece of furniture or safety equipment.

A STANDALONE computer operates independently of a network, using its own resources without relying on external connections for functionality.

In networking, a segment refers to a group of nodes that share the same communications channel for their traffic on the network, facilitating data transfer within that specific segment.

SNEAKERNET refers to the practice of physically carrying data on portable storage devices to transfer it between computers, as opposed to transferring it over a network. This term highlights the manual and offline method of data exchange.

Soft skills refer to personal attributes and interpersonal skills that enhance an individual's interactions, job performance, and career prospects. Unlike hard skills (which are specific and measurable abilities), soft skills are more subjective and harder to quantify, but equally important in the workplace.

A protocol is a standardized set of rules that allow devices to communicate with each other in a reliable and efficient manner, ensuring data is transmitted accurately and in the correct order.

A NIC, or Network Interface Card, is a hardware component in a computer that allows it to connect to a network and communicate with other nodes. It is essential for network connectivity.

A mail server refers to a dedicated server responsible for managing the storage and transfer of email messages, ensuring their delivery to the appropriate recipients.

Transmission media refers to the means through which data are transmitted and received, such as wires, cables, radio waves, etc. It does not refer to the process of data analysis, data storage, or data visualization.
